This invention relates to a method of assembling valve mechanism within apassage in a lubricant feeding nipple, and to a tool for assembling the same.

An object of my invention is to provide a tool which during a single operation will advance a coil spring into the passage in a lubricant feeding nipple, and broach the in ner wall of the nipple to provide lugs for re- '10 taining the spring therein.

iAnother object of my invention is to provide a tool having broaching teeth and a coil spring retaining seat, or pilot.

Another object of my'invention resides in providing a tool having broaching teeth, and means beyond the ends of the teeth for engaging atcoil spring, said means having clearances thereln in alignment with the broaching teeth. a

Another object of my invention resides in the method by which a coil spring is assembled and secured within the passage in a lubricant feeding nipple to exert pressure againsta valve member. c

Another object of my invention resides in the method by which a coil spring, is com- 'pressed within the passage of a lubricant feeding nipple, and lugs are broached from the inner wall of the nipple to secure the spring under compression within the passage therein during a single operation after assembling a ball valve within the passage.

Referring to the drawings by characters of reference 10 represents a plate forming a 'part of a punch I in inverted position, below a holder 11 which tive position at the finish is operated by suitable mechanism ofany well known type.

The plate 10 is provided with a recess 12 1 into which a portionof the nipple fits, being the nipple is thereby and other objects will appear here- 7 view 'of the press for holding a nipple CORPORATION, OF CHICAGO, ILLINOIS, A. CORPORATION OF DELAWARE.

of substantially the same configuration as the outside of the nipple. The nipple 13 has a reduced inlet end 14 and an outlet end 15, and a passage extends therethrough consisting of a chamber 16, and passages 17 and 18 of decreased diameters. The nipple is also provided with hexagonal sides 19, and when inserted into the recess 12 of the same shape, secured within the plate for the purpose hereinafter 'set forth.

The holder 11 is arranged so that it can becentered directly above the nipple, and is provided with a recess 20 into which one end of-the shank 21, of the broachi-ng tool 22 is removably secured. A set screw '23 extends through an aperture in the wall of the holderalllld lengages a flattened portion 24 on the s an r.

The outer end of the shank is 'providedlands are formed as broaching teeth 27 which are provided with inwardly extending rakes A pilot 29 extends from the end of the Ly greater than the diameter of the shank taken atthe central point of the clearances 25 adjacent which the ribs extend. The end 32 of the' pilot is formed substantially flat to engage the transversely extending end 33 of a coil spring 34, as hereinafter described.

The ribs 31 are provided near their'outer ends with inwardly extending shoulders 35 which provide a seat which will engage the circular end of a coil spring 34 as shown in Fig 1.-

outlet end thereof. The ball will engage the when the nipple 13 has been placed in the i inner wall of the nipple at the junction between the passage 17 and the chamber 16. A coil spring 34 is then inserted into the passage through the outlet end and will engage the ball 36. The breaching punch carried by the holder 11 is then'positioned centrally above the chamber 16 of the nipple, and

I power is applied to move the punch toward the nipple. As this movement continues the end of the pilot is projected into the coil spring and the shoulders engage the circular strand at the outer end of the coil spring. Further continued movement of the punch will compress the spring" against the ball. within the passage, in advance of the broaching teeth, and the broaching teeth will engage the inner wall of. the nipple adjacent the chamber and will punch out strips thereof -curling them inwardly within the chamber forming lugs. These lugs will curl inwardly through the clearances in the pilot. The longitudinal position of the lugs determine the tension of the spring against the ball,

the same.

and the punch is moved into the nipple sufficient distance to projectithelugs at the position therein to create the desired pressure desired the mechanism operating the punch is reversed, aiid the punch is withdrawn from the hi ple, during which movement the outer end '0 the spring will engage the lugs as the seat formed by the shoulders on t e pilot passes therethrough. i f

It will thus be seen that the spring is compressed within the passage in the nipple in advance of the broaching teeth and so held during the formation of the lugs, which lugs will secure the spring compressed within the passa e, exerting suflicient pressure against I the ba 1 to normally close the passage through In 1gs. 2 and 4 I have shown-a modified type ofspring in which the transverse end.33 is engaged by the flat end of the pilotwhen the punch is moved toward the nipplel-=The spring is compressed and the lugs are simultaneously formed in this instanceas previously described, and other than the difl'erence in the pilot engages the the manner in which coil spring, the operation and arrangement Various changes may bena'de in details of construction shown and described withoutdepartingjrom the spirit of my. invention and the scope of niy claims.

What I claim is 1. A method of assembling valve 'mecha; nism within a passage through a lubricant reend of the passage in the nipple, inserting a coil spring for engaging the closure member into the. outlet end of the passage in the nipple, compressing said' spring, breaching lugs from the wall of the nipple and concurrently increasing the compression of said spring so that the upper end thereof is maintained a predetermined distance from the fixed ends of the lugs, and then releasing said spring to permit the upper end thereof to rest on said lu s.

That method of assembling valve mechanism within a passage through a lubricantreceiving nipple for high pressure lubricating apparatus which consists of holding a nipple, inserting a closure member into the ceiving nipple consisting of holding a nipple, I inserting a closure member into the outlet outlet-end of the passage in the nipple, insert- I ing a coil spring into the passage through the outletend thereof, compressing said spring, and then breaching lugs from the wall of the nipple to support the outer end of said spring and concurrently increasingthe pressure of V L said spring.

'3. The method of assembling valve mecha- I nism within a passage through a lubricant receiving nipple consisting of holding a nipof the nipple and maintaining the outlet end of the spring a predetermined distance from Y the'walljend of said lugs during the broaching operation.

4. That method of assembling v'alve mechanism within a passage through a lubricant "receivingnipple which consists of holding a ;n1pple with its outlet end in exposed posi-,

tion, then inserting a Valve member into thepassage through said outlet end, then 'inserting a spring through the'outlet end', then co'm- I pres sing thespring'against the valve member, and then broaching lugs from the" wall of the nipple and. maintaining the outlet end of lugs.
